Timeskip1 year. Obito has finished training. Obito POV

'You have finished your training, Obito. We should  go for your friends. They are closeby.'

'Ok, Madara.' I speak in my mindscape. Then I form shadow clones. 

"Alright guys, locate Kakashi and Rin, then teleport me over." I say.

"Alright, Boss!" They say as they depart. I have matured my sharingan fully. I have the Mangekyo, Eternal Mangekyo, and even the Rinnegan. My abilities are almost limitless. After five or ten minutes, I am teleported to a clearing with a lot of Mist ANBU and Jonin. I see Kakashi and Rin fighting. I activate my sharingan. I see the chakra of the three tails inside Rin. So they made her a time bomb. Good thing I can heal that. I see her body getting ready to jump in front of Kakashi's chidori. To save The Village, probably. I love her, and I can save her. As Rin jumps in front of Kakashi, his eyes widen. I use my top speed, and grab Kakashi's and Rin's wrists as they both jump forward. I turn them in the air, and let them down. (Like when Kakashi stops the fight between Naruto and Sasuke before he leaves the village) I am wearing a hood, so they can't see my face. 

"Who are you?" Kakashi asks.

"I'll tell you later, just give me Rin for a sec, so I can safely remove the Three Tails." I say.

"How do you know my name, and how did you know I have the Three Tails?" Rin inquires. 

"As for your name, we know each other very well. As for the Three Tails, my lovely lady, the sharingan. Now Kakashi, cover for me while I heal her, then I'll take care of the enemies." I say.

"Ok." Kakashi says as he proceeds to cover me. I concentrate, then activate the Rinnegan. I slowly extract the Three Tails chakra. I get into the Three Tails mind.

'Hey, do you mind getting out of my friend. I loosened the seal quite a bit, and I'll teleport you once you get out, so please?' I ask him.

'Sure kid. I didn't want to be in here anyway.' Three replies.

'Thanks man.' I say as I teleport him to his home lake. I exit the mindscape.

"Alright, Kakashi, fall back. I've got this." I say. "Susanoo!" The blue and yellow warrior appears. I take all the ninja out in a few swoops. My former teammates watch in awe.

"Who are you, and how do you know our names?" Rin asks, a bit scared.

"Why my dear Rin..." I say as I walk towards her. "I need you to watch as I become, Hokage, right?" I take off the hood. Kakashi almost faints, and Rin tears up.

"O-Obito?" Rin asks, with tears in her eyes.

"Yup. Good to see you guys again!" I say cheerfully. I smile. That is, until I receive a hard punch to the gut.

"YOU BAKA! WHY DID YOU KEEP ME WAITING! I THOUGHT YOU WERE DEAD!" Rin sobs.

"I'm sorry, Rin. I would've come earlier, but my entire right side was crushed, so it took a while to heal. Also, stupid Madara made me finish my training.

"Wait, your saying you met Madara Uchiha?" Kakashi says.

"Yup, old man was on his deathbed, but he mixed our bodies, so now I'm the Madara Uchiha jinjuriki! He helped me get the Mangekyo sharingan, the Eternal Mangekyo sharingan, and even the Rinnegan! It's awesome! I'll show you guys once we get back to the village." I say. "Now grab on, I'm going to teleport us." I say as I sink into the Kamui world.
